Thank you for responding. I've tried to reset it. No menu is showing. Nothing is showing on the screen except "Read Verify Scan" with various items: Battery Check, Volts, Level, Charge OK, Canceled showing on a list, and at the bottom Menu to Continue. I tried clicking on anything to get that Menu to Continue to respond to something, but this thing is totally frozen on that screen.
What is happening is NO BUTTONS work, no resetting works, toggling the hold button doesn't work, the backlight stays on continously, there is no getting out of the mode it is in; I even tried updating thinking that would jar something loose, but nothing gets the frozen screen out of the window.
